Claims (10)
einen festen Abschnitt, der an dem Rahmen befestigt ist;
eine Kettenführung zum Berühren der Kette, um die Kette umzuschalten;
einen beweglichen Abschnitt, der über dem festen Abschnitt angeordnet ist und be festigend die Kettenführung hält;
eine erste und zweite Verbindung, die zwischen und schwenkbar verbunden mit dem festen Abschnitt und dem beweglichen Abschnitt verbunden sind, wobei die erste und zweite Verbindung relativ zueinander bewegbar den beweglichen Abschnitt mit dem festen Abschnitt verbinden;
einen Kabelverbinder, der an der ersten Verbindung zum Sichern des Steuerkabels befestigt ist; und
gekennzeichnet durch
einen Hilfsvorsprung, der vom Kabelverbinder hervorsteht, zum Berühren des Steu erkabels in einer Position, die vom Kabelverbinder hinreichend beabstandet ist.1. A front derailleur device that is attachable to a frame of a bicycle and is operable by an operator that is transmitted through a control cable to switch a bicycle chain between a plurality of front sprockets, comprising:
a fixed portion attached to the frame;
a chain guide for touching the chain to switch the chain;
a movable section which is arranged above the fixed section and holds the chain guide be fastened;
first and second links pivotally connected to the fixed portion and the movable portion, the first and second links movably connecting the movable portion to the fixed portion;
a cable connector attached to the first connector for securing the control cable; and
marked by
an auxiliary protrusion protruding from the cable connector for touching the control cable in a position sufficiently spaced from the cable connector.
erste und zweite Führungsflächen, die sich im wesentlichen vertikal bezüglich des Fahrrads erstrecken, und
eine obere Oberfläche, die sich zwischen den ersten und zweiten Führungsflächen erstreckt, und dass
die erste und zweite Verbindung, der Kabelverbinder und der Hilfsvorsprung die erste Führungsfläche überlappen, wenn von einer Richtung senkrecht zu den ersten und zweiten Führungsflächen betrachtet.3. A front derailleur device as defined in claim 1 or 2, characterized in that the chain guide comprises:
first and second guide surfaces which extend substantially vertically with respect to the bicycle, and
an upper surface extending between the first and second guide surfaces, and that
